Goal: Using my Webcam (Aukey 1080p LM1E) for Video Communication with MJPEG 1920x1080 30fps under linux.
Problem:
My first Problem was that whenever i tried qv4l2 to change the settings from YUYV 640x480 30fps to MJPEG 1920x1080 30fps it did reset to the YUYV settings. But with v4l2-ctl --device /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=MJPG i could save the settings.
But the weird thing is whenever i use cheese or a Video Communication in my Browser, it settles back on YUYV.
Attempts:
At first I only tested it with cheese and a video communication, so I thought the webcam disconnects and resets the settings every time. For this reason I created a udev rule that resets the settings to MJPG SUBSYSTEM=="video4linux", KERNEL=="video[0-9]*", ATTRS{product}=="AUKEY PC-LM1E Camera", ATTRS{serial}=="AUKEY PC-LM1E Audio", RUN="/usr/bin/v4l2-ctl -d $devnode --set-fmt-video=width=1920,height=1080,pixelformat=MJPG"
and it worked. Every time I unplugged and reconnected my webcam, the MJPG settings would load. But unfortunately it didn't solve the problem because it still sets the format to YUYV when I use cheese or my video communication. My next attempt was to use something else so I used webcamoid and guvcview. The result was confusing because it didn't change back to YUYV.
Question: Any idea how I can solve this problem? Iam really confused because there must be a reason why cheese and browser video communications are using YUYV?
